Walsh is scheduled to play his last show with Kansas in Sioux City, Iowa on August 16th. Kansas also has a series of fall dates set, starting with an appearance at the Oklahoma State Fair in Oklahoma City on September 12th. The band hasn't announced how they will handle his absence. Kansas will continue their summer tour with a show in Baytown, Texas on Thursday.

Steve's tenure with Kansas dates back to the early 1970s. He joined in 1972, when the group was still called White Clover, and remained until 1981. Kansas officially split up three years later. In 1985, Walsh joined founding Kansas drummer Phil Ehart and guitarist Rich Williams in reviving the group, and has been on board ever since.

Walsh is the voice behind Kansas' biggest hits, including "Carry On Wayward Son," "Dust in the Wind," and "Point of Know Return."
